Letters Patent No. 74,840, dated-Feruargf25, 1868;, anfealated .February 13, 1868.

LITHOGRAPHIG PRESS.

10 ALL WHOM IT MAY CONGERN:

Be it known that I, CHARLES MAURICE, of the city, county, and State of New York, have invented a new andimproved I iithographic and Autograpbic Press; and I do hereby declare that the following is a full, clear, and exact description thereof, which will .enable others skilled ,in the -art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in`which Figure 1 represents anvertical longitudinal section ofiny improved press, the plane of section being indi, cated' by the line :c z, ig. 2. i i

Figure 2-is a plan or top view, partly in section, of the same.

Smilarletters of reference indicate corresponding parts.

This invention relates Ato a lithographie or other printing-press, in which the stone o1` block is held -i n an adjustable frame, Wbichicah be expanded or contracted, soias to be adapted to stones `of different width,

The pressure is applieid by a roller, which is placed over the frame across the sanne, and which ismade heavy by a weighted frame, which is suspended froui'it', and `in which the roller turns. The stone or block,' when ready for printing, iscovered with the paper or materialupon which the print" is to be transfe`rred,and then a canvas cover istolded over the latter.' The roller is then vgradually turned byineans of a crank its end, and is by this revolving motion fed along the stone orblo'ck, from one end of he frame to the other, thereby pressing with equal force upon every portion of the paper, and'insuring an equal print.

The stone can be adjusted up and down, so as to come underl the pressure of-the roller.- The weight of the frame which is suspended from'thc roller should be vvery heavy; still,itwill be very easy to turn the roller and thereby presstbe paper on 'the stone. Y* Twovor three or more stones or blocks may be laid alongside 4of, `each other, in the same fratrie, soth'at they will all be operated upon by o'ne'roller.l Thus, after the'roller hasr'paszed over one stone, the paper is removed, an i the stone reiuked and new paper applied, while the roller passes over the other blocks or` stones. Such a machine can, therefore,ibekept, by theV aid of two persons, in continuous motion, or, rather, continually working. i

A represents a wooden or othermetal frame, of-suitable length and-width, to support the adjustable casing for the stone. 'It is standing upon legs B lwhch are sufticiently strong, andof therequired'length Cisthe casing for the stone. It consists of uprightsideand end-pieces for sari-'L unding the stfoneand ot' a solid bottom, or of simple cross-pieces, in place of the latter, for securing it upon the'frame'A. To make the 'casing C laterally adjustable for stones yor blocks ofyarixilis widths, it hasrbeeuY madeof two pieces, `as .if it were Vcut along its longitudinal axis. .The bottom pieces-arc slotted, and are fastened by screws a a to the frame A. It is easily understood that-the lateral adjustment can be performed withfacility 'and quickness. D is a roller, which is laid across the casing C, fand from theA ends of which a heavily-weighted frame, E, isi-suspended, the weightsF onthe latter being reryy heavy, so tli'at the roller D will be' steadiedr'in its motions. The *stone or block G, from which the impression" is to be taken, rests upon a loose frame, or, upon ,barsQEl` H, andean be raised or lowered by means of screws Ii b, so as to be brought under the pressure of the roller D,y as shown. The latter is provided with a. crank, c, at one or eachend, as' shown. A; frame, I', which is pivoted near to the end of' the frame C, holds the canvas, paper, onrcloth cover, which is letdo'wnupon the paper whilethe roller passcp over the same. One such frame can be arranged at each end of the frame C, or one for 4eachstone, of which any desired number can be used, onebcinf.r laid alongsideA the other.'

The operatibn andmode of working will be fully un-derstoodfrom the foregoing. The velocity-of the passage ofthe roller from end to end ofthe stone can bevaried by varying its diameter, y

Having thus described my invention', what I claim as new, and desire to sec-ure by Letters Patent, is-

1. The case C, when arrangedvso-that it can be adjusted forwider orv narrower stones or blocks, :substantially as hereivnshown and described. I

2, T he case C, when consisting 'of' two pieces or halves, whichare laterally adjustable on the frame A, and

I whenc'ombined with the up-and-down adjustable frame or plates H, all arranged and operating substautiallyas herein shown and described. i

3. The roller D, when connected with the weighted frame E, and with'the stone or block G', so that by rotary motions of the roller, the latter will be moved over the stone,. 6 it will come in Contact with andpress upon each part of the paper and stone, and will notbe drawn over the same, thereby insuring'n neatness 'of workmanship.

4.` The adjustable frames C and H, in combination with the roller D and weigbtedframe E, `all made and operating substantially-'as and for the purpose herein shown and described.

C. MAURICE.
